Questions
How big is the INAAmplifierRev2 PCB?
It measures 99.9 × 49.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the INAAmplifierRev2 use?
58 parts, built around the INA129P and LM358. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the INAAmplifierRev2 KiCad files?
From the JayBernstein/EMG-Controlled-Prosthetic repository on GitHub, at the commit this page was made from: the board is Hardware/Amplifier/Probe_Amplifier_Rev2/INAAmplifierRev2/INAAmplifierRev2.kicad_pcb and its schematic Hardware/Amplifier/INA129-Amplifier/INA129-Amplifier.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the INAAmplifierRev2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask JayBernstein before reusing the design.
